引言对现代磁带录音装置特性提出的高要求,使得在设计和使用存贮装置时要相当准确地估计它的抗干扰性。众所周知,这种估计是非常不容易的,必须考虑到影响系统特性和干扰强度的大量因素。磁带录放系统中的干扰和噪声是由于录音载体的几何特性、磁特性以及传带机构的
INTRODUCTION The high demands placed on the characteristics of modern tape recording devices make it quite accurate to estimate their noise immunity when designing and using storage devices. It is well-known that this estimation is not easy and must take into account the large number of factors that affect system characteristics and the strength of the interference. The disturbance and noise in the tape recording and reproducing system are due to the geometric characteristics of the recording carrier, the magnetic characteristics and the
